  2. Helmet Visor and Sunscreen In the current Regulation 22, in § 6.15.3.4., we should test the luminous transmittance as specified below : Visors shall have a luminous transmittance τv ≥ 80%, relative to the standard illuminant D65. A luminous transmittance 80% > τv ≥ 50%, measured by the method given in § 7.8.3.2.1.1., is also permissible if the visor is marked with the symbol shown in figure 2 and/or with the English words “DAYTIME USE ONLY”. The luminous transmittance shall be measured before the abrasion test.

  3. Helmet Visor and Sunscreen We find on the market some helmets equipped with integrated sunscreen (5). Thesesunscreens are not approved according to ECE R22-05, and modify the luminous transmittance. Moreover, helmet visors (3) which not met luminous transmittance criteria of ECE R22-05 could be found, as spare parts, on the market. 1- ECE R22-05 transparent visor Tv ≥ 80% 2- ECE R22-05 tinted visor 80% > Tv ≥ 50% 3- Visor supplied as spare parts with helmet (but without type approval) 1 2 5 3 4 4- ECE R22-05 visor 5- Sunscreen integrated in Helmet, without type approval

  4. French proposal • We will propose for next meeting a document to amend current ECE R22.05 in order to take into account this innovation. • This document will be based on the following principles : • Authorises in ECE R22-05 tinted visor with lower light transmission • Creates the sunscreen definition in ECE R22-05
